Sourcing knitwear is not the same as buying cut-and-sew jersey. Flat-knit construction — the process behind sweaters, cardigans, and technical knitwear — requires machine programming, yarn procurement, and panel-by-panel production that simply cannot be compressed the way a fabric-print run can. A brand used to 6-week jersey turnarounds will miss every season if they apply the same timeline to knitwear.

The numbers are straightforward: sampling takes 10–14 days in-factory, then shipping and approval rounds add another 1–2 weeks per revision cycle. Bulk production runs 45–60 days depending on complexity and volume. Ocean freight from Turkey (Mersin port) to the US East Coast is approximately 14 days, plus 3–5 days buffer for port handling and customs clearance. From approved tech pack to goods in your warehouse: roughly 100–120 days — plan for 4 months minimum.

A brand that wants Fall/Winter on the retail floor by September 15 must count backwards from that date: subtract 7–10 days DC processing, 3–7 days customs clearance, 14 days ocean, 60 days bulk production, 7 days pre-production sample, and 3–4 weeks for proto sampling and approval. That puts the tech pack delivery date in late January — and the first factory conversation in December or January at the latest.

Understanding the Lead Time Stack

Every stage in the supply chain adds time, and those stages are sequential — you cannot start bulk production before sampling is approved. Here is the full stack:

Stage	Duration	Notes
Tech pack to proto sample approval	2–4 weeks	Includes your review and revision rounds; each revision cycle = +1–2 weeks
Pre-production sample	1 week	If needed; can skip if proto is fully approved and unchanged
Bulk production	45–60 days	Varies by style complexity and order volume; yarn sourcing adds 5–10 days before knitting starts
Ocean freight (Turkey → US East Coast)	~14 days	FCL from Mersin; allow 3–5 additional days buffer for port congestion and vessel schedule shifts
US customs clearance	3–7 days	Depends on entry type, UFLPA review status, and CBP exam selection at port of entry
Inland delivery to DC/warehouse	2–5 days	Depends on your logistics setup and proximity to port of entry
Total: tech pack to warehouse	~100–120 days	Plan for 4 months minimum; 5 months for complex programs

Month-by-Month Buying Calendar

The calendar below maps key decision points for a US brand selling across multiple seasonal windows. Use it to identify where you are now and what actions are overdue or on schedule.

JAN

Spring/Summer Sampling Deadline

For brands selling Spring/Summer to wholesale retailers, proto samples must be approved by end of January to allow time for bulk production and June delivery. If your SS proto is not started by January, June delivery is at risk. This is also the window to open conversations about Fall/Winter — share concept direction and confirm factory capacity before it books up.

FEB

SS Bulk PO Deadline / FW Line Planning Begins

Spring/Summer bulk purchase order deadline for early-June US port arrival. With proto approved in January, the PO should be placed by mid-February to begin production on schedule. Simultaneously, begin Fall/Winter line planning: yarn selection, construction direction, and initial tech pack development. FW yarn commitments made now lock in availability for premium fibers.

MAR

SS Bulk in Production / FW Tech Pack Prep

Spring/Summer bulk production is running. Monitor progress weekly. Finalize FW tech packs and send them to the factory — early delivery of FW tech packs (March vs. April) gives you a buffer for revision rounds without jeopardizing the FW sampling schedule. Review FW yarn samples and confirm colorways.

APR

FW Sampling Begins

Fall/Winter proto sampling is in production at the factory. Turkish holiday note: Eid al-Fitr (Ramazan Bayramı) date shifts each year with the Islamic calendar — confirm the exact date before setting your sampling deadline and add a one-week buffer around the holiday window. The days immediately before Eid are often disrupted as workers travel. Factor this into your proto delivery expectation.

MAY

FW Proto Approval Window / SS Bulk Arriving

FW proto samples arrive for your review. Evaluate construction, gauge, stitch quality, and fit against tech pack specs. Send consolidated, written revision feedback — one complete round of corrections is far more efficient than piecemeal emails. Spring/Summer bulk is clearing US customs and arriving at your warehouse or 3PL this month.

JUN

FW Salesman/Pre-Production Sample / SS Production Wrap

With FW proto approved, the factory produces salesman samples or pre-production samples in confirmed bulk colorways. These represent what bulk will look like — evaluate color accuracy against your lab dip approvals, trim and label placement, and any construction details corrected from proto. Spring/Summer production wraps; review any carry-over or repeat order needs.

JUL

FW Bulk PO Deadline for September Delivery

Bulk purchase order must be placed by mid-July for a September US port arrival. This is a hard deadline — a PO placed in August pushes delivery to October or November. At PO placement: transfer the 30% deposit, confirm the size/color breakdown in writing, and verify that your approved PP sample is the production standard on file. Production begins once yarn stock is confirmed.

AUG

FW Bulk in Production / Holiday Q4 Sampling Begins

Fall/Winter bulk production is running through August. Turkish holiday note: Eid al-Adha (Kurban Bayramı) is the longer Eid holiday — 4 days plus travel time, with a production impact of approximately 7 days. Its date also shifts annually on the Islamic calendar — confirm the exact date with your factory and build a buffer if it falls in your FW production window. Simultaneously, Holiday and Q4 proto sampling begins now for brands targeting December floor dates.

SEP

FW Bulk on the Water / Holiday Q4 Proto Approval

Fall/Winter container is sailing from Mersin toward US East Coast ports. Final inspection should be completed and balance payment (70%) transferred before vessel departure. Holiday/Q4 proto samples arrive for review and approval. Any revision round here has direct consequence on the Holiday bulk PO timeline — approve and move fast.

OCT

Holiday Q4 Bulk PO Deadline / SS 2027 Planning Starts

Holiday and Q4 bulk purchase order must be placed by late October for December US port arrival. This is the last viable window for ocean freight — a November PO will not arrive in time for December retail. Fall/Winter goods arrive at your warehouse this month. Begin Spring/Summer 2027 concept direction and open factory conversations — the planning cycle starts again.

NOV

Holiday Q4 Bulk in Production / FW Reorder Window

Holiday production is running at the factory. If Fall/Winter is selling ahead of plan and you have fast-moving styles, the FW reorder window is now — any reorder placed in November can be air-freighted in time for late December or used for January restocking. Surface-level knitwear reorders are feasible; complex new styles are not at this stage.

DEC

Holiday Q4 Bulk Arriving / SS 2027 Sampling Begins

Holiday and Q4 goods are clearing US customs and arriving at your warehouse or 3PL. Spring/Summer 2027 proto sampling should begin by late December for brands targeting May-June delivery. Share final SS 2027 tech packs with the factory before year-end — factories returning from New Year with confirmed programs move faster than those starting cold in January.

Turkish Holidays That Affect Production

Two Islamic holidays affect Turkish factory production significantly each year. Because they follow the lunar calendar, their Gregorian dates shift forward by approximately 10–11 days annually. Always confirm the current year's dates before setting PO or sampling deadlines.

Eid al-Fitr (Ramazan Bayramı)

A 3-day national holiday at the end of Ramadan. Factory closure is typically 3 days, but production impact is approximately 5 days — workers travel in the days beforehand, and the period immediately following the holiday sees reduced pace. Confirm the exact date each year before finalizing your sampling schedule. In recent years, Eid al-Fitr has fallen in late March or April, placing it directly in the FW sampling window.

Eid al-Adha (Kurban Bayramı)

A 4-day national holiday — the more impactful of the two Eid holidays for production. With travel time factored in, the production disruption is approximately 7 days. In recent years, Eid al-Adha has fallen in June, placing it in the middle of Fall/Winter bulk production. This is the single most disruptive holiday for FW delivery schedules. Confirm the exact date with your factory and add buffer before committing your FW bulk PO deadline.

Republic Day and National Holidays

Turkey observes several single-day national holidays: April 23 (National Sovereignty and Children's Day), May 1 (Labor Day), May 19 (Commemoration of Atatürk), August 30 (Victory Day), and October 28–29 (Republic Day). Each is a factory closure of one day. Individually, the impact is minor — but if multiple fall within a production window, the cumulative effect can add several days to completion time.

New Year and Winter Slowdown

Turkish factories typically observe January 1 as a national holiday. Unlike some Asian manufacturing regions, there is no extended winter shutdown in Turkey — production resumes normally in January. This is an advantage for US brands on tight FW timelines: you can realistically start a January tech pack delivery and expect the factory to be operational and responsive.

Common Planning Mistakes US Brands Make

These errors come up consistently with brands that are new to overseas knitwear sourcing — or that are applying jersey timelines to flat-knit programs.

Starting FW Tech Packs in April Instead of February

An April tech pack delivery puts proto sampling in May, approval in June, and bulk authorization in July. That is a September-or-later production completion — which means October or November US port arrival at best. September retail floor date is missed. The fix: FW tech packs delivered to the factory in January or February, not April.

Not Building Revision Rounds into the Schedule

Every proto revision cycle adds 1–2 weeks: 10–14 days for the factory to re-sample, plus shipping time. A brand that assumes one flawless proto and plans their bulk PO accordingly will be 2–4 weeks behind schedule after a single revision round. Plan for at least one revision round in your sampling timeline, and build the corresponding buffer into your bulk PO deadline.

Placing Bulk PO Before Pre-Production Sample Approval

It is tempting to push bulk authorization ahead of PP sample approval to save time — but this is a false shortcut. Color, size spec, and construction surprises discovered at bulk are expensive and sometimes unfixable without remaking the order. The PP sample is your last practical quality gate before the factory commits yarn and machine time to your full production run. Approve it in writing first.

Forgetting Customs Clearance Time in the Backward Plan

Many sourcing plans calculate "factory shipment date = retail floor date minus ocean transit." US customs clearance adds 3–7 days, and CBP exam selection can add 5–10 more. A standard entry during non-peak port periods takes 3–5 days. A CBP intensive exam during peak October port season can take 10 days or more. Always include customs clearance in your backward plan from the retail floor date.

Assuming "45-Day Bulk" Starts on PO Date

Bulk production lead time begins when yarn is in-house and approved — not when the PO is signed. Yarn sourcing from Turkish mills typically adds 5–10 days before the knitting floor starts your order. For specialty yarns (cashmere, recycled blends, novelty fibers), that gap can be 2–3 weeks. When you place a bulk PO, ask the factory for a specific production start date and confirm yarn arrival timing.

If You're Starting Now — What's Still Achievable

Reading this in June 2026, here is a realistic assessment of what each seasonal window still looks like:

FW 2026

Difficult, but a Capsule is Possible

If a Fall/Winter proto has not been started yet, a September retail floor date for a full FW collection is not achievable via ocean freight. However, a small FW capsule (3–5 styles, limited colorways, existing construction types) may still be viable with a fast approval process and air freight for samples. Be honest with your factory about the compressed timeline and ask what is genuinely feasible in their current production queue — do not plan around a best-case scenario.

Holiday 2026

Still Achievable — Move Fast

Holiday and Q4 knitwear is still achievable if you place a bulk PO by late July. That means proto sampling now (June), proto approval in late June or early July, and bulk authorization immediately after. This is a tight window with no room for revision rounds — your tech pack needs to be production-ready before you send it. If your design requires development rounds, start today.

SS 2027

Ideal Window — Start Today

Spring/Summer 2027 knitwear is in the ideal planning window right now. Beginning the tech pack process in June for a January 2027 bulk PO gives you ample time for sampling, revision rounds, and pre-production approval — with a May or June 2027 US delivery. This is how knitwear sourcing is supposed to work: starting 10–11 months ahead of retail floor date gives you options and leverage.
